[0034] In the traditional liquid-cooled air conditioner structure, it generally uses the air-cooling method for heat dissipation. Its air-cooling heat dissipation structure generally has an air inlet and outlet method of flat inlet and flat outlet. Usually, a heat dissipation water tank structure is set at the air inlet, and the coolant inside the heat dissipation water tank is cooled by the air flow at the air inlet. In this traditional cooling method, the hot air inside the box body cannot be discharged in time and effectively, the cooling effect of the coolant is limited, and there is a lack of corresponding heat dissipation structure to deal with the high temperature generated on the compressor main board, which is likely to accelerate the aging of the components inside the entire air conditioner structure.

[0035] The present utility model proposes a liquid-cooled air conditioner heat dissipation structure 100 to solve the above problems. Please refer to Figures 1 to 4 .

[0036] Please refer to Figures 1 to 3 , in the traditional liquid-cooled air conditioner structure, it generally has an air inlet and outlet method of flat inlet and flat outlet. Usually, a heat dissipation water tank structure is set at the air inlet, and the coolant inside the heat dissipation water tank is cooled by the air flow at the air inlet. In this traditional cooling method, the hot air inside the box body cannot be discharged in time and effectively, the cooling effect of the coolant is limited, and there is a lack of corresponding heat dissipation structure to deal with the high temperature generated on the compressor main board, which is likely to accelerate the aging of the components inside the entire air conditioner structure. In this embodiment, first, the air inlet method of the traditional air conditioner is changed on the housing 2, air is introduced into the installation cavity from the horizontal air inlet surface 221 surrounding the housing 21, and then the hot air inside the installation cavity is discharged upward through the air guiding structure on the end cover 23. The hot air rises and is discharged, which can effectively improve the air discharge effect inside the installation cavity. And heat dissipation water tank structures are provided at both the air inlet surface 221 and the position of the end cover 23, making full use of the air flow at the two air inlets, and as much as possible making the air flow at the two air inlets take away the heat of the coolant in the heat dissipation water tank structure. And the circulating cooling structure is connected to the compressor drive board 1 inside the installation cavity. During the process of the circulating cooling structure circulating the coolant, it can take away the heat on the compressor drive board 1, thereby cooling the compressor drive board 1. The setting of the above structure can effectively promote the external discharge of the heat inside the housing 2, while improving the performance of the air conditioner, it can also effectively extend the service life of its internal components.

[0037] Such as Figure 2As shown in the figure, the radiator water tank structure includes a first radiator water tank 3 and a second radiator water tank 4. The first radiator water tank 3 is vertically installed in the installation cavity and is located on one side of the air inlet surface 221. When the air flow passes through the air inlet surface 221, the first radiator water tank 3 can be cooled synchronously. The second radiator water tank 4 is arranged inside the end cover 23. During the process of the air guiding structure exhausting the internal gas of the housing 2 upward and outward, the coolant inside the second radiator water tank 4 can be cooled. At the same time, the first water outlet 32 on the first radiator water tank 3 is connected to the second water inlet 41 on the second radiator water tank 4, so that the first radiator water tank 3 and the second radiator water tank 4 are connected in series to form an integral water cooling device. During the circulation process of the coolant, after two cooling processes, the cooling effect of the coolant is further improved.

[0038] As Figure 1 and Figure 2 shown, one end of the diversion component 5 in the circulating cooling structure is connected to the first water inlet 31 on the first radiator water tank 3. The first water inlet 31 and the first water outlet 32 are respectively arranged at both ends of the first radiator water tank 3. As Figure 2 shown, the coolant is introduced from the first water inlet 31 at the lower right corner of the first radiator water tank 3 and is connected to the second radiator water tank 4 from the first water outlet 32 at the upper left corner. By setting the positions of the first water inlet 31 and the first water outlet 32 in this way, the coolant can have a sufficient flow path in the first radiator water tank 3, so as to better promote the dissipation of its heat. And after the coolant is cooled by the first radiator body and the second radiator body at the same time, its temperature has dropped sufficiently. Then, the coolant after cooling is used to cool the drive plate cooling structure 6, and a better cooling effect can be achieved.

[0039] In order to improve the cooling effect on the compressor drive plate 1, as Figure 2 and Figure 3 shown, in this embodiment, the compressor drive plate 1 is installed on the mounting plate part 611 of the first frame body 61. Both the mounting plate part 611 and the mounting frame part 612 are made of materials with good heat conduction effect. Specifically, in order to increase the heat exchange area, the entire serpentine heat dissipation tube 62 is installed in a sunken manner on the mounting plate part 611, and a plurality of heat conduction iron cores 64 are arranged outside the mounting plate part 611. The coolant cooled by the second radiator water tank 4 flows into the serpentine heat dissipation tube 62. The serpentine heat dissipation tube 62 will absorb the heat on the compressor drive plate 1 and discharge the absorbed heat through the circulation of the coolant.

[0040] Considering that the overall temperature of the compressor drive board 1 is relatively high during operation, simply relying on overall air cooling and the above-mentioned water cooling structure may not achieve good cooling for it. For example, Figure 3 and Figure 4 As shown, in this embodiment, an independent air cooling structure is provided for targeted cooling treatment. Specifically, an inclined frame part 613 is provided on the mounting frame part 612, and a second fan 63 is provided on the inclined frame part 613. The second fan 63 is arranged in an inclined shape along with the inclined frame part 613, and its air outlet surface still corresponds to the serpentine heat dissipation pipe 62, but there is a certain inclination angle between the air outlet surface and the mounting plate part 611. When the second fan 63 operates, it can drive the hot air on the serpentine heat dissipation pipe 62 to be discharged upward. The independent air cooling structure can further improve the cooling effect of the compressor drive board 1, which has a good promoting effect on improving the overall cooling performance of the air conditioner.

[0041] The output end of the pump body 51 on the support frame 53 is connected to the first water inlet 31, and its input end is connected to the third water outlet 522 of the liquid storage tank 52. During actual operation, the pump body 51 pumps the coolant into the first radiator 3. After being air-cooled by the air inlet surface 221, the coolant flows into the second radiator 4 and is subjected to secondary air cooling at the end cover 23. The coolant after secondary air cooling is introduced into the serpentine heat dissipation pipe 62 through the second water outlet 42 to dissipate heat from the compressor drive board 1, and then flows into the liquid storage tank 52 through the third water inlet 521, and then is circulated and pumped by the pump body 51. For example, Figure 2 As shown, in this embodiment, the third water outlet 522 and the third water inlet 521 are simultaneously arranged on both sides of the upper and lower ends of the liquid storage tank, so as to enable the reflux coolant to be fully mixed with the coolant stored in the liquid storage tank 52 during the flow of the coolant, making the output temperature of the coolant more uniform.

[0042] The liquid storage tank 52 and the first frame 61 are arranged close to the rear end of the housing 2, forming a relatively large heat dissipation space inside the housing 2. For example, Figure 3 and Figure 4 As shown, at the same time, an air inlet part 224 corresponding to the second fan 63 is provided on one end surface of the rear end part. When dissipating heat from the compressor drive board 1, the second fan 63 can be used for air guiding to dissipate heat from the compressor drive board 1.

[0043] The air guiding structure is set as a fan structure. Specifically, for example, Figure 3As shown, there are two first fans 232, which are installed at two mounting holes 231 of the end cap 23. When the two first fans 232 work, they will promote the hot air inside the housing 2 to be discharged outside the end cap 23, and at the same time, the external air enters the housing 2 from the air inlet surface 221.

[0044] As Figure 1 and Figure 2 shown, there are a plurality of diversion holes 222 at the air inlet surface 221 and the end cap 23 to form a ventilation structure. When the entire device housing 2 structure dissipates heat, an air conduction path can be formed to achieve a better cooling effect.

[0045] As Figure 1 shown, when the entire structure is installed, a connection can be formed through the mounting structure 223 and the external structure.

[0046] The above is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the technical concept of the present invention, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
